[FOLLOW UP] Creating Normal Maps in Blender

blanchsb, theluthier 

Shawn had asked a question during this stream about whether Blender could be used to create normal maps. I later ran across the linked course by jlampel explaining how to do it in 2.79 but I think it still applies to 2.8. I haven't viewed the entire course yet but the few videos that I did watch pan out in 2.8 as well.

    Hey Paul, that course should still be about the same in 2.8! If you find any way in which the change throws you off, just let me know. 

    • Yeah still works perfectly fine in 2.8 👌🏻 Only issues I had with baking was due to my own lack of experience, all your techniques work exactly as you taught. Awesome course btw super comprehensible  😊

  • ppaulhaynes1955 Thank you for the followup! This will be awesome to have in my tool belt. I will add it to my watch list.

    Maybe I misunderstood the question during the stream. I thought the question was "can Blender convert black and white bump maps to normal maps easily / with nodes?" We can definitely bake normal maps from geometry as well as bake black and white bumps to normal maps but it's not an ideal conversion process imo. Often I find myself with a black and white map wishing I could convert it to a normal map with a simple node which currently isn't possible as far as I know.

    • You can convert black & white maps to normal maps with Substance Designer, it’s like Blender nodes on steroids 😎 also the amount of procedural noises and grunge is insane

      I know the teacher in you avoids other software but maybe you should try it for a personal project sometime, you can get an one month trial for free 😉

      I haven't tried this myself, but I'm pretty sure it's doing the same as Blender's bump node. There's just no way to get 3D  information out of 2D information! Not without making a whole lot of assumptions, which may work for plugging into a normal map socket, but it won't be functionally different than a bump map beyond the slightly slower performance.
